Bolverk

A high-ranking demon who continually impedes Dante's progress throughout Dumary Island. He commands the twin wolves Freki and Geri, wields a gigantic spear, and is missing an eye; all attributes shared with the Norse god Odin. He takes on the appearance of a demonic skeleton and uses shadow-based powers.

He first sends Freki and Geri on their own to stop Dante; when this fails, he battles Dante himself in the Throne Room. After a tough battle, he retreats, allowing Dante passage. He encounters Dante a final time in the Underworld, but is defeated. Upon his defeat, he breaks into numerous pieces, melting into the floor.

In terms of gameplay, his battles are very similar to those against Nelo Angelo in Devil May Cry (1). It is not quite clear whether he serves Arius, or holds a personal grudge against the Son of Sparda...
